If you want to change this behavior or add help text, choice limitation, and etc when setup argparse,you can use ```@task.set_argument``` decorator and pass the same arguments you pass when using argparse.

And now you can only run from Tokyo or Osaka but cannot run from KyotoAlso you must run in an int value speed.

For positional arguments, taskr matches its name and argument of function automatically.But for optional arguments, you must assign ```dest``` to make taskr understand which argument of functionshoule map to.

### ```@task.pass_argparse_namespace``` decorator

If your task function has set ```pass_argparse_namespace``` by this decorator,then all the argument of argparse should be decalred explicitly. (i.e. taskr won't discover for you automatically)Also the argument passed into your task function is only the "Namespace" comes from argparse

It gives you a str 'Hello World' with loght red color and white background.Also you can use ```console.info```, ```console.error```, ```console.success```, ```console.highlight```,and ```console.prompt``` to print messages
